Remove schema “CollectionPage”

Hello,

Thank you for contacting Rank Math and bringing your concern to our attention.

The CollectionPage is a subset of the WebPage Schema. ​​​​​​If you would like to remove this type of Schema, you can use and customize this filter:

add_filter( 'rank_math/json_ld', function( $data, $jsonld ) {
        unset($data['WebPage']);
    return $data;
}, 99, 2);

Please note that the filter above applies to your whole site, but you can insert a conditional statement to apply it only to some of your pages.

And here’s how you can add a filter/hook to your WordPress site:

Hope that helps.

Thank you.
